SD Cards - PSoC to Z80
Log from 3-Chip Z80 Design
Now that we can read SD cards and have an I/O interface in place from the Z80 to do I/O mapped access to the SD card it's time to hook the two pieces together. To do this we will need to look closer at how Grant's code request blocks. The loader...

Researching Options - Power
Log from Boxies - Low power RF LED Cubes
I'd like to avoid frequently replacing batteries or running power wires to the boxes if at all possible, as such, I'm either wanting to have ultra-low power components and 'smarter' operational times (eg only show LED's when someones in the room) or...

Requirements Easily found when misplacedBig enough to hold easily but not too big that it's cumbersomeShould have a battery compartment so that unskilled personnel can replace batteries without having to open up the housingRoom enough for the necessary...

Ordered Some More Parts
Log from Motion Controlled Cabinet Light
I decided that once I get this project working well, that I might make several for family and friends that might need something like this. To that end I placed an order for some HC-SR04 (Ultrasonic Ranging Module) and the HC-SR501 (PIR Sensor) modules...

Initial LED Selection
Log from E-Bike Light
When I set about this project the first thing I wanted to work out was what LED I was going to use, as this would drive the requirements of everything else in the project, driver, lens, heatsinking, etc. Due to personal preference I decided that I wanted...

The 2019 PiDP-8
Log from PiDP-8/I
It's already out since July, but just to log the improvements:There's actually a lot to learn about kit-making: how to prevent beginners from messing up soldering a computer kit for the first time. So it was time for a revamp of the PiDP-8, putting in...

Wrote a very basic command interface with three commands:W - Write the EEPROMR - Read the EEPROMB - Bounce an LED across the RPP-UIO-16 cardThe result looks like this:Write to the EEPROM Read from the EEPROM 0000 00 01 02 03 04 05 06 07 08 09 0a 0b 0c...

Sun Tracker 2 Revision 1 - Prototyping Board
Log from SunTracker 2 Revision 3
With the compass functionality tested on a breadboard, the next step is to transfer it to a universal prototyping board, adding a status display and IO expansion ports to drive a LED ring that simulates the horizon. For the board, I am going to use the...

We Have Blinkenlights!
Log from 2:5 Scale KENBAK-1 Personal Computer Reproduction
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...

The resistive touchscreen

July was a tough month, and August is no different. Due to some components arriving late, I've only been able to start my work on the Hackaday.io project with considerable delay. So I had to catch up with everything and squeeze the entire development...

More 2369, with more caps !
Log from Hackaday TTLers
Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...

Version 1 Testing
Log from Ultra Low Power Feather Development Board
Version 1 of the hardware arrived, and I have been testing it. Almost immediately, I discovered I had made a connection mistake on the 3.3V regulator, and the system would not run normally from battery power. I desoldered that part, and by providing...

AES-256 Is Not Enough: Breaking a Bootloader
Log from ChipWhisperer®: Security Research
I'd been pushing hard trying to get a demo of how you can break an AES-256 bootloader. This type of bootloader is often used in products for protecting firmware updates and a good demonstration of why you should care about side channel attacks as an...
